There are ways to prevent DDoS, First is to get a GOOD HOST, Dont buy from a company that looks suspicious, for example a 4$ per month host and the advertisement says it has DDoS Protection. Its too good to be true, And obviously lying. Second is to block the ports that aren't used.

Learn to secure. If you have basic security knowledge, some d-bag little script kiddie can't compromise your server. If you don't have that capacity, get someone that does to join your team. And get a good host. You get what you paid for after all.

In short: Don't buckle under the threat of some noob and his LOIC. And I know that this topic hasn't been responded to in a minute, but too bad.

yeah as tripper said don't be scared in DDOS attacks all hosting now a days have ddos protection up to 20gbps but those hackers what can wipe ruined your database, server, back ups, that should you to be scared.
